I have a surplus of organic grown Jerusalem artichockes. What would be a reasonable price per 500gr if I sold the at the local growers' market ? Thanks for your help' Andrée

It depends what you mean by bulk. I have just bought a kilo on Trade Me from a lady in Napier.

I promise they will grow. My tips - to harvest them only one plant at a time - or 'bandicoot' a few tubers from the side. Really fresh tubers - I mean today's - don't need peeling, just scrub. When replanting, save the smoothest tubers. I kept them going for four or five generations and managed to get an easy-peel strain going. If you have too many [and who doesn't?] goats love the tops and chickens love the tubers. Eating toast with artichoke soup tends to reduce the anti-social after-effects. Warning! If you leave a whole plant in the ground from year to year, it will still grow but you will end up with amazingly complex unpeelable tubers.

VERY invasive, but we do have them here for sale in our community gardens
